6.11 Tone Parameters
This subsection describes the device's tone parameters.
6.11.1 Telephony Tone Parameters
The telephony tone parameters are described in the table below.
Table 6-47: Tone Parameters
Parameter Description
Dial Tone Duration [sec]
[TimeForDialTone]
Duration (in seconds) that the dial tone is played.
FXS interfaces play the dial tone after the phone is picked up (off-
hook). FXO interfaces play the dial tone after the port is seized in
response to ringing (from PBX/PSTN).
The valid range is 0 to 60. The default time is 16.
Notes:
 During play of dial tone, the device waits for DTMF digits.
 This parameter is not applicable when Automatic Dialing is
enabled.
Stutter Tone Duration
[StutterToneDuration]
Duration (in msec) of the Confirmation tone. A Stutter tone is
played (instead of a regular dial tone) when Call Forward is
enabled on the specific port or when a Message Waiting Indication
(MWI) is received. The Stutter tone is composed of a Confirmation
tone (Tone Type 8), which is played for the defined duration
(StutterToneDuration), followed by a Stutter Dial tone (Tone Type
15). Both these tones are defined in the CPT file.
The range is 1,000 to 60,000. The default is 2,000 (i.e., 2 seconds).
Notes:
 This parameter is applicable only to FXS interfaces.
 If you want to configure the duration of the Confirmation tone to
longer than 16 seconds, you must increase the value of the
parameter TimeForDialTone accordingly.
 The MWI tone takes precedence over the Call Forwarding
Reminder tone. For detailed information on MWI, refer to
Message Waiting Indication on page 428.
Web: FXO AutoDial Play
BusyTone
[FXOAutoDialPlayBusyTone]
Determines whether the device plays a Busy/Reorder tone to the
PSTN side if a Tel-to-IP call is rejected by a SIP error response
(4xx, 5xx or 6xx). If a SIP error response is received, the device
seizes the line (off-hook), and then plays a Busy/Reorder tone to
the PSTN side (for the duration defined by the parameter
TimeForReorderTone). After playing the tone, the line is released
(on-hook).
 [0] = Disable (default)
 [1] = Enable
Note: This parameter is applicable only to FXO interfaces.
